These antistatic agents are highly effective liquid additives for antistatic finishing of expandable polystyrene and polypropylene.

The following different processes are basically available for the addition of the antistatic additive:

  • Addition of the antistatic agents during pre-expansion in a continuous process via the steam line admission point
  • Mixing the plastic and the antistatic agent prior to the pre-expansion process in a batch mixer (e.g. at the same time as the special dye is added for dyeing the plastic)
